摘要
目的探讨肺腺鳞癌影像学表现是否具有特殊性；瘤内的腺癌、鳞癌成分与Ｘ线表现及预后的关系。方法复习经手术切除、病理确诊为腺鳞癌者５１例，５２个病灶。全部病例均有正侧位胸片，ＣＴ２３例，ＭＲＩ６例。按照镜下腺癌成分含量分为＜４０％、４０％～６０％、＞６０％三组。结果（１）腺鳞癌的影像学表现：中央型３例；周围型４８例，占９４．１％。肿瘤直径２～１５ｃｍ，平均５．７ｃｍ。均呈分叶状、边缘光整１９例，占３９．６％；边缘不光整但无明显毛刺１８例（１９个病灶），占３７．５％；有毛刺１４例，占２９．２％；偏心空洞８例，占１５．７％；胸膜皱缩１２例，占２５．０％。（２）瘤内成分含量与Ｘ线表现的关系：部位、边缘、密度、胸膜皱缩在三组之间差异无显著性。结论本组结果表明，肺腺鳞癌以周围型多见，肿瘤无特异性Ｘ线表现；腺癌成分含量与Ｘ线表现和预后无明显关系。
Objective To study if there are characteristic radiologic features of adenosquamous carcinoma (ASC) of the lung and correlations of histo pathologic components with radiologic findings and prognosis. Methods Fifty one pathologicall confirmed ASC cases (52 foci)were reviewed. All had chest radiographs, CT scans were available in 23 cases and MRI in 6 cases. These cases were subdivided into three groups according to the amount of adenocarcinoma component on microscopic manifestations: less than 40%, 40%～60%, and more than 60%.Results (1) Radiologic findings: In three cases, the tumor was of central type and in 48 cases (94.1%) of peripheral type. The size of tumor varied from 2 to 15 cm in diameter (mean, 5.7 cm). All the peripheral tumors were lobulated. In 19 cases (39.6%) the tumors were well demarcated, but poorly defined in 18 cases (19 foci) (37.5%) and spiculated in 14 cases (29.2%). Eccentric cavities with thickened wall were seen in 8 cases (15.7%) and pleural tag in 12 cases (25%). (2) Correlations between the amount of adenocarcinoma component and radiologic features: There were no statistically significant differences among the three groups with regard to tumor location, margin, and pleural tag. Conclusion The radiologic findings of ASC are not specific; the most common finding is a peripheral mass. The amount of adenocarcinoma component is not significantly related with the radiologic features and prognosis.
